Omron K8AK-PM Series Monitoring Relay, 220 to 480V AC Voltage Sensing Range, 10 to 55 Hz Frequency Sensing Range - K8AK-PM2

This monitoring relay is designed for voltage and phase monitoring applications in three-phase power supplies. The K8AK-PM2 model provides advanced features within a compact design, measuring 22.5mm in width, 90mm in height, and 100mm in depth. The relay operates across a voltage sensing range of 220 to 480V AC, ensuring reliable performance under various environmental conditions.

Features & Benefits

• Supports both three-phase 3-wire and 4-wire configurations
• Monitors overvoltages, undervoltages, phase sequence, and phase loss
• Equipped with two SPDT output relays rated for 5 A at 250 VAC
• Output status indicated by LEDs for easy monitoring
• Operating temperature range from -20 to +60°C for diverse applications
• Easy installation with screw terminals suitable for DIN rail mounting

Applications

• Used in industrial facilities for monitoring electrical systems
• Ideal for equipment protection against voltage fluctuations
• Implemented in critical machinery where phase loss detection is essential
• Suitable for use in global power environments due to switchable specifications

How is the performance of this relay affected by environmental conditions?

It operates effectively in temperatures ranging from -20 to +60°C and can withstand storage temperatures from -25 to 65°C, ensuring reliability in various settings.

What types of connections are required for operation?

It requires connections to L1, L2, and L3 for three-phase 3-wire mode or L1, L2, L3, and N for the three-phase four-wire mode, emphasising the importance of correct wiring configuration.

Can the overvoltage and undervoltage settings be adjusted?

Yes, both the overvoltage and undervoltage thresholds can be set between -30% to +25% of the rated input voltage, enabling precise control based on specific application needs.

How can phase loss be accurately detected with this relay?

Phase loss detection is achieved through monitoring voltage drops in any phase, allowing for a quick response to mitigate potential equipment damage.
